“…. 0.95 [9] where R = n ch /n tot < 1. The number of muons produced in an air shower depends not only on the primary energy and air density, but also on the total particle multiplicities and in a much more sensitive way [10] of the charged over all particle ratio of hadronic interactions.…”

Abstract. Currently the uncertainty in the prediction of shower observables for different primary particles and energies is dominated by differences between hadronic interaction models. The LHC data on minimum bias measurements can be used to test Monte Carlo generators and these new constrains will help to reduce the uncertainties in air shower predictions. In this article, after a short introduction on air showers we will show the results of the comparison between the updated version of high energy hadronic interaction models with LHC data. Results for air shower simulations and their consequence on the comparison with air shower data will be discussed.

“…A fast one-dimensional hybrid method has been used to simulate air showers by Alvarez-Muñiz et al (2002a). The models QGSJET 98 and two versions of SIBYLL (1.7 and 2.1) have been applied to describe the hadronic interactions.…”

Abstract. The model dependence of the development of extensive air showers generated by high-energy cosmic-ray particles in the atmosphere is studied. The increase of proton-proton and proton-air inelastic cross-sections and values for the elasticity are varied in the hadronic interaction model QGSJET. Using the CORSIKA simulation program, the impact of these changes is investigated on air shower observables like the average depth of the shower maximum Xmax and the number of muons and electrons at ground level. Calculating the mean logarithmic mass from experimental Xmax values, it is found that a moderate logarithmic increase of the proton-proton inelastic cross-section from σ inel pp = 51 mb at E 0 = 10 6 GeV to σ inel pp = 64 mb at E 0 = 10 8 GeV and an elasticity, additionally increased by 10% to 15%, describes the data best. Using these parameters, the mean logarithmic mass ln A derived from Xmax measurements is compatible with the extrapolations of the results of direct measurements to high energies using the poly-gonato model.

“…During the simulation, all sub-showers below a given energy threshold are replaced with a sample from this data base. The Bartol [7] approach consists of a shower library of pion-initiated showers for different injection depths, energies and zenith angles. Nucleons are Figure 1.…”

Air shower simulations are essential for interpreting data from cosmic ray experiments. At highest energies though, a microscopic treatment of a whole shower is not possible any more, since it would require a huge amount of CPU-time. We review hybrid approaches of air shower simulation which try to overcome this problem without giving rise to artificial fluctuations as generated by the thinning algorithm.
